我有国家列表：
http://vocab.nic.in/rest.php/country/json
而我正在尝试通过Bloodhound建议引擎获取country_id和country name. O尝试以下代码：
var countries = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.obj.whitespace('country_name'),queryTokenizer: Bloodhound.tokenizers.whitespace,limit: 10,prefetch: {
url: 'http://vocab.nic.in/rest.PHP/country/json',filter: function(response) {
return response.countries;
}
}
});
$('#my-input').typeahead({
hint: true,highlight: true,minLength: 1
},{
name: 'states',displayKey: 'value',source: countries.ttAdapter()
});
哪个不行.我应该如何更改代码以使其工作？
解决方法
// instantiate the bloodhound suggestion engine
var countries = new Bloodhound({
datumTokenizer: function(countries) {
return Bloodhound.tokenizers.whitespace(countries.value);
},remote: {
url: "http://vocab.nic.in/rest.PHP/country/json",filter: function(response) {
return response.countries;
}
}
});
// initialize the bloodhound suggestion engine
countries.initialize();
// instantiate the typeahead UI
$('.typeahead').typeahead(
{ hint: true,minLength: 1
},{
name: 'countries',displayKey: function(countries) {
return countries.country.country_name;
},source: countries.ttAdapter()
});
前置输出
笔记：
>您的服务器上的数据=“prefetch”.> data from outside =“remote”
